摘要
通过单轴拉伸与平面拉伸试验,得到了柔性接头弹性件橡胶材料"三阶五项式"超弹本构模型参数,通过有限元计算证明了该模型的优越性。为了获得柔性接头弹性件材料剪切模量随容压的变化规律,设计了双轴加载试验装置和表征柔性接头弹性件的三重片试件,进行了压缩剪切联合加载试验及有限元数值模拟。试验结果发现,橡胶材料的剪切模量并没有随压力的升高而减小,该现象与计算结果吻合较好。
Planar and uniaxial tests were implemented to achieve 3nd order-5th item strain model constant of the elastomer and it is proved this model was superior to others.In order to measure the shear modulus of the elastomer at different pressure,that biaxial device and three-board sample,were designed and the shear-compression test was conducted this process was simulated.The test results show that the shear modulus of the elastomer will not decrease with enhancing compression which agreed with well with the simulation.
